Today morning suddenly my phone hanged and turned off automatically.
Later turning on manually again, then pressing on wifi and hotspot button. It's not turning on!
Apology for the experience. For now, request you to please visit the service center. Please share the RMA via PM if you have any issues during service or any issues confirm via PM as well.
I'm facing the same problem currently. My WiFi and Hotspot were not working and yesterday suddenly my phone switched off now it's not turning back on and shows a Corrupt message on screen.
